ABSTRACT

The systems, methods and apparatuses described herein provide a computing environment that includes secure time management. An apparatus according to the present disclosure may comprise a non-volatile storage to store a synchronization time and a processor. The processor may be configured to generate a request for a current time, transmit the request to a trusted timekeeper, receive a digitally signed response containing a current, real-world time from the trusted timekeeper, verify the digital signature of the response, verify that the response is received within a predefined time, compare a nonce in the request to a nonce in the response, determine that the current, real-world time received from the trusted timekeeper is within a range of a current time calculated at the apparatus and update the synchronization time with the current, real-world time in the response.
